Embodiment
Preferred embodiment of the present utility model is illustrated below in conjunction with accompanying drawing, it will be appreciated that described herein excellent
Select embodiment to be merely to illustrate and explain the utility model, be not used to limit the utility model.
Embodiment：As shown in Figure 1-2, a kind of flexible board circuit board for LCD MODULE of the utility model, including
Flexible PCB 1, circuit board package plate 2 and set casing 6, one end of flexible PCB 1 are fixed on circuit board package plate 2, and
Flexible PCB 1 is wound around circuit board package plate 2, and the inner side of circuit board package plate 2 is provided with central shaft 5, and central shaft 5 is centered around half
Outside conductor cooling piece 4, and the bottom of central shaft 5 is fixed on set casing 6, is provided between central shaft 5 and circuit board package plate 2
The spring 3 of annular, and on the both ends difference fixing circuit board package plate 2 and central shaft 5 of spring 3, the side shell inside one of set casing 6
Side is fixed with several radiating fins 7, and is covered with heat emission hole 10 outside set casing 6.
